The third guide post 511 is a square shaft structure, and the third guide post hole 510 is a square hole structure having the same cross-sectional shape as the third guide post 511, so as to ensure that the third guide post 511 does not rotate during the up-and-down movement process.

A dovetail groove is formed at the bottom of the fourth rack 506 and is in sliding fit with the first guide rail 507.

As a further explanation of this example, referring to fig. 5 to 8, the motor 201 further drives a reciprocating mechanism 600, and the reciprocating mechanism 600 includes: a movable slide rail 601, a guide sleeve 602, a second crank 603, a third connecting rod 604, a second guide rail 605 and a second slide block 606;

one end of the movable slide rail 601 is mounted at one end of the worm 501 through a bearing, the other end of the movable slide rail 601 is disposed in the guide sleeve 602 and moves along the guide sleeve 602, the guide sleeve 602 is fixed to the machine body 101, the guide sleeve 602 is hinged to one end of the third connecting rod 604, the other end of the third connecting rod 604 is hinged to one end of the second crank 603, and the other end of the second crank 603 is fixedly connected to the worm 501;

the bottom of the supporting frame 102 is configured with the second sliding block 606, the second sliding block 606 moves along the second guide rail 605, and the second guide rail 605 is fixedly connected with the machine body 101.

According to the invention, the motor 201 drives the reciprocating mechanism 600 to enable the first massage head 105 and the second massage head 106 to reciprocate left and right in the horizontal direction, so that the massage range is expanded, the scraping function is realized by simulating hands of a person, more foot massage functions are realized, acupuncture points of feet are stimulated in different modes, the blood circulation is promoted, and a better health care effect is achieved.

According to the invention, the worm 501 is connected with one end of the movable sliding rail 601 through a bearing, and meanwhile, the crankshaft 203 is fixedly connected with the end part of the second crank 603 when the worm rotates, so that the distance from the axis of the worm 501 to the center of the guide sleeve 602 is changed in the process of rotating the second crank 603, and the axis of the worm 501 can perform reciprocating linear motion relative to the machine body 101, so that the first massage head 105 and the second massage head 106 are driven to perform reciprocating motion, the effect of reciprocating massage of the sole is achieved, and the process of pushing the massage sole by hand of a person is simulated.

The guide sleeve 602 is provided with a round hole, and is in sliding fit with the movable slide rail 601.

As a further explanation of this example, referring to fig. 1 and 2, the first guide post 209 has a square shaft structure, and the first guide post hole 211 has a square hole structure having the same cross-sectional shape as the first guide post 209.

The present invention ensures that the first guide post 209 does not rotate during the up and down motion.

As a further explanation of this example, with reference to fig. 4 and 5, the second gear 508 is centrally threaded to threadably engage the threaded rod 509.

The invention realizes that the second gear 508 rotates to change the height of the screw 509.

As a further explanation of this example, referring to fig. 5, the second slider 606 is dovetail-shaped, and the second guide rail 605 is provided with a dovetail groove.

The two sliding blocks are matched to ensure that the sliding process of the second sliding block 606 is stable and does not fall off.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
